Becoming a hermit.

I broke up with my boyfriend because we had a text argument. We were supposed to be moving slowly after a huge mental break down. Im afraid my friends will remove me from thier lives If I continue to bring stress to them. I can hardly go back to the one I love because of fears of reliving the anxiety and stress that made me break up in the first place. It wasn't all bad but I can't go back without thinking another misunderstanding in a text or opposing view point on something will make him want to distance himself again. I don t know if should move on or be brave and try another whack at a relationship. Too scared to make any moves
